To a/ZZ whom t may concern:

Be it known that I, MARTIN A.l JOHNSON, a

citizen of theUnited States, residing at Stoughf ton, in the county ofDane and Stateof Wisconsln, have invented certain new and usefulImprovements in Top-Box Fasteners for- Wagons; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it `appertains tomake and use the same, reference being had to the accom-v panyingdrawings, and to the letters of reference marked thereon, which form apart of this specification.

My invention relates to vehicles, and especially to the devices employedto fasten upon a wagon body the top box or boxes used to give additionalheight to said body.

The invention consists in improvements in the construction andarrangement of the fasteners.

Heretofore, various devices have been proposed and used but certainpractical objections to them have arisen, which I aim to obviate. Iprovide the Wagon body with a Stationary screw threaded iron with whichengages fit) movable threaded piece, carried by the top In the drawings,Figure lillustrates a wagon body and a top box provided with fastenersembodying my'invention. Fig. 2 is a vertical transverse section on anenlarged scale. Figs. 3 to 9 inclusive, show Inodiiied-forms of fas`teners.

The body A is of any suitable construction, and is provided with theusual holding dogs a, and braces B. The top box A rests upon the upperedge of the body A, and has straddlers or cleats a fitting inside thebody to preventlateral displacement of the box. The second top box A2 issimilarlyconstructed. To fasten either one or both of these boxes inplace, I provide the body with a piece C which has a cylindrical portionprovided with a screw thread, preferably located in an off-set, asshown. This may be a male thread, as in Figs. l, 2, 4, 5 and 8, or afemale thread, as in Figs. 3, 6 and 7. The piece C may be an extensionof the braces B, as in Figs. l, 2 and 5, or a separate ironas in Figs.3, 4, 6, 7, and S. The top box is provided with an iron the body.

D, having a flange containingan opening adapted to register with thethreaded portion of vthe iron C when the top box is placedupon in theiron D, and' receives a nut E. as in Figs.

The opening may be a notch, as 55 l,v 2, 4, and'8. 'When a female threadlis cut 6o in thel piece C,ja screw bolt E islpassed through the openingin the iron D, and eny 'which Apasses through the irons and theboxsides, and isV secured by a nut f. Theseries of holes CZ, permits theirons to lap over an intermediate 'top box A', as clearly shown in Fig.2, or to be adjusted for a single box only, by passing the box rodsthrough a lower hole in the irons. vAfter placing the top box upon thebody, it is preferable to tighten up the rods first, and then draw theirons, C, D, together by means of the screw-threaded connections.

By using the word iron I do not intend to limit myself to that metalonly, the word being used in its broader Sense, as applied to v ametallic fitting.

Lock nuts e may be used when necessary, as shown in Figs. 2 and 5.

In Fig. 7, a split pinee is shown driven through a transverse hole inthe bolt E to prevent it from working out.

. The nut shown in Fig. 8 has a head provided with an oblique win gwhich abuts against the side of the wagon body.

The advantages of this construction are that it prevents a personsclothes from catching on the nut when getting into or out of the wagon,and also, that the iron C is not so liable to be bent when the boxes arepiled on top of each other in shipping the wagons.

In Fig. 9, I have Shown a fastener similar to that in Fig. 1 except thatthe slot or notch is turned toward the back of the Wagon. The

IOO

upper end of the iron C is threaded, the nut E screwed on, and then thethread at the end of the iron above the nut is destroyed or In utilated,or the end of the iron is upset, so that the nut cannot be lost in useor removed. Vith this construction, the fastener D is slipped under thenut, the nut is constantly in place and ready for service the box rod ispassed through the proper hole, and the nut is screwed down. Thisconstruction may also be used when the iron D is bolted to the wagonbody, as it may be in some cases.

The advantage of using a fastener with a nut on an upwardly projectingbolt is, that the jar and shaking of the wagon cause the nut to settledownward on the bolt, and thereby tighten itself.

Having thus described niy invention, what I claim, and desire to secureby Letters Patent, isf- 1. The combination with a Wagon body and topbox, of an iron rigidly secured to the Wagon body and having at itsupper end an outwardly projecting screwthreaded portion, a downwardlyprojecting fastener attached to the top box and having in its lower endan opening to register with the iron on the body and a threaded pieceadapted to engage with said iron and hold the fastener thereon, substantially as described.

2. The combination with a wagonbody, of a piece C having a screwthreaded portion, a top box, rods F, irons D having a series of holes dfor said rods, and flanges containing holes to receive the threadedportions of the piece C, and nuts to hold said parts together,substantially as described.

3. The combination with a Wagon body and top box, of an upwardlyprojecting threaded iron attached to said body, a fastener attached tothe box and adapted to engage with said iron, and a n ut to secure thefastener, said nut; having an oblique wing adapted to rest against theside of the body, substantially as described. y

In testimony whereof I affix my signature iu presence of two witnesses.

M. A. JOHNSON.
